A 422 HTTP status code should be returned after the submission of an invalid form. Some libraries including [Turbo](https://github.com/hotwired/turbo/pull/39) rely on this behavior and will not display the updated form (containing errors) unless this status code is present.
Rails also [recently switched to this behavior ](https://github.com/rails/rails/pull/41026) by default for the same reason.
I propose to introduce a new helper method rendering the form and setting the appropriate status code. It makes the code cleaner:
```php
// src/Controller/TaskController.php
// ...
use Symfony\Component\HttpFoundation\Request;
class TaskController extends AbstractController
{
public function new(Request $request): Response
{
$task = new Task();
$form = $this->createForm(TaskType::class, $task);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$task = $form->getData();
// ...
return $this->redirectToRoute('task_success');
}
return $this->renderForm('task/new.html.twig', $form);
}
}
```
